Monotube Shocks at Vorshlag Motorsports

Vorshlag is primarily a performance automotive suspension manufacturer and reseller. We are well known for making Vorshlag spherical top mount camber plates and shock mounts - which many consider the best in the world, and we sell thousands of sets per year. Being in this line of work we also see a large variety of shocks and struts from all damper companies, and we have been developing, building, repairing, testing, racing with and selling monotube dampers for over a decade.



Vorshlag Motorsports has become known for selling high quality monotube dampers for street driven, autocross, rally and road course driven vehicles. We have tested and raced with virtually all modern shocks and have chosen to sell what we feel are the brands with the best combination of strengths. We work with racers and dual purpose car owners in every racing class in motorsports, from rally to autocross, time trial to club racing, and hill climb to land speed racing. If you have unusual needs, we even have unusual solutions.

Below are some of the shock companies we have worked with over the years. Some of the "grayed out" brands are ones we used to sell but that have stopped selling dampers in the United States for one reason or another - that information is for reference only.

          

Bilstein: In 2012 Vorshlag became one of a very small number of Bilstein Motorsports dealers in the USA, which gives us access to the full line of their Bilstein OEM-style monotube shocks, their "tuner" line of PSS series shocks, as well as the Bilstein Motorsports line-up. These Motorsport models include offroad and racing shocks as well as shock components, to potentially make bespoke dampers. This can allow us to make one-off shocks, to help racers with cars that are not supported by the major manufacturers. Look for more exciting things from this line-up in the future.

          

MCS: In early 2013, Vorshlag became a dealer for Motion Control Suspensions (MCS). This company is run by the folks who ran Moton for 15 years, and JRZ before that. We have worked with MCS to develop new solutions and perfect existing fitments. We have installed their internal singles, internal doubles, and remote reservoir MCS shocks. We stock a number of their products as well.

        

AST: Many people know that we have had a long relationship with AST Suspension, a Dutch shock maker with products shown above. From 2006-2009 Vorshlag was the sole U.S. importer and distributor of this brand. From 2009-on we have been one of their biggest full line AST dealers in the USA, and continued to help develop, repair and even manufacture strut bodies for some AST models.

          

Moton: In 2011 AST Holland bought the assets of Moton Suspension (see products above), and now both shock brands are built in the same factory in Valkensvaard, The Netherlands, but they are still distinctly different shocks with significant model differences. We started selling Moton shocks at that time, and have had great racing success using these dampers on our own racing cars as well as customer cars in NASA Time Trial, SCCA Solo and club racing.

Between these MCS, Bilstein, and Bilstein Motorsports brands we offer multiple shock options for most car models, with a full array of features and a wide spectrum of pricing. The various models are listed in a bit more detail below. If this is a bit overwhelming, don't worry, we can help. Feel free to call and talk to one of our tech experts (972-422-7170) or e-mail us your questions to info@vorshlag.com.

 Shock Model Breakdown - features, pros and cons

The data below explains what brands and models we recommend for various racing classes and other uses, based on the many decades of racing experience by the folks here at Vorshlag. This listing includes the standard shock series that our various shock vendors build and import to North America, some of which are custom built to order. There are some other variations made for some custom applications, but most of what we sell falls into these categories. Please call or drop us a line if you don't see something you need among these models, or if you want to know more.
